5017A V/17A A list of Supergiant Stars D Egret Bull. Inform. CDS 18 82 1980 1980BICDS..18...82E Stars, supergiant This catalogue is a compilation of about 5000 stars classified as supergiants (class I or II) in the literature. The following information is given: DM and HD identifications, coordinates, photometry, radial velocity and MK classification

CSI designation number=1 The CSI designation (see Ochsenbein et al. 1980) is made of 3 parts: the zone, the number, and a code. For a positive number, the code indicates which Durchmusterung the zone and number refer to: - BD (Bonner Durchmusterung) for 0 <= code <= 19 - CD (Cordoba Durchmusterung) for 20 <= code <= 39 - CPD (Cape Durchmusterung) for 40 <= code <= 59 A negative number (constructed from 1950 right ascension) is assigned for non-DM stars. --- HD Henry Draper Catalogue Designation --- m_HD Multiplicity index on HD number; a '/' indicates a group of 2 HD numbers --- RAh Right Ascension 1950 (hours) h RAm Right Ascension 1950 (minutes) min RAs Right Ascension 1950 (seconds) s u_RAs for poor position (accuracy 1arcmin) --- DE- Declination 1950 (sign) --- DEd Declination 1950 (degrees) deg DEm Declination 1950 (minutes) arcmin DEs Declination 1950 (seconds) arcsec GLON Galactic longitude deg GLAT Galactic latitude deg n_Vmag Variability or Duplicity indicator --- Vmag Visual magnitude mag u_Vmag Uncertainty flag (:) on Vmag --- q_Vmag Quality indicator on Vmag number=2 the quality number (1=poor, 4=good) comes from the UBV catalogue by Nicolet (1978); --- B-V Colour mag q_B-V Quality indicator on B-V number=2 the quality number (1=poor, 4=good) comes from the UBV catalogue by Nicolet (1978); --- U-B Colour mag q_U-B Quality indicator on U-B number=2 the quality number (1=poor, 4=good) comes from the UBV catalogue by Nicolet (1978); --- Gflag 'G' when Geneva photometry exists --- Uflag 'U' when uvby photometry exists --- RVel Radial Velocity from Wilson (1953) or Evans (1967) km/s q_RVel Quality on Radial Velocity (A=good, E=very poor) --- n_Sp Dispersive system used, or quality from Houk's catalogue (when Sep='X') number=3 The MK classification from N. Houk (1975, 1978) includes a quality from 1 (good) to 4 (poor), a '+' for spectra classified in other sources, and 'X' when several spectra were available. When Sep is a '/', the classification is from Jaschek (1978) --- Sep Separator ('X' when Sp is from Houk) --- Sp Spectral classification number=3 The MK classification from N. Houk (1975, 1978) includes a quality from 1 (good) to 4 (poor), a '+' for spectra classified in other sources, and 'X' when several spectra were available. When Sep is a '/', the classification is from Jaschek (1978) --- Francois Ochsenbein CDS 1995Jul12 UNKNOWN UNKNOWN * June 1980: catalogue prepared and archived at CDS * 12-Jul-1995: the catalogue was reformatted at CDS: => elimination of record headers "5017A1" => creation of a dedicated column for the ':' uncertainty flag u_Vmag which was previously embedded in the Vmag column => addition of the standard documentation V_17A.xml
